il 'o aw whpm t may concern:

Be it Vltnown that I, MARIO COSTA, a citizen' of the United States, residing at East lValling'ford, in the town of Wallingford, county of New Haven, State of Connecticut, have invented new and useful Improvements in Rubber Heels, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to a new and improved rubber heel, having for its object, among other things, to provide a heel of resilient material that may be readilyr attached and detached from a shoe and designed so that it may be used either on the right or left shoe.

To these, and other ends, my invention consists in the rubber heel, having certain details of construction and combinations of parts, as will be hereinafter described and more particularly pointed out in the-claims.

Referring to the drawings, in which like numerals ofreference designate like parts in the several figures;

Figure 1 is a plan view, partly in section, of my improved heel;

Fig. 2 is a sectional view thereof, taken upon line 2 2 of Fig. 1, with a portion of the shoe attached;

Fig. 3 is a front elevation of the heel;

Fig. 4 is ai plan view of the retaining plate; and

Fig. 5 is` an end elevation thereof.

Referring to the drawings, the numeral 1 designates a portion of a shoe and 2 a retaining plate permanently connected. therewith by means of the prongs 3, which project into the shoe and are clenched substantially as shown in Fig. 2. This retaining plate is preferably made of sheet metal with a flange 4 upon its front end, in which is rotatably mounted the turn button 8. The surface 5 of this plate is so formed that its outer edge is in a lower horizontal plane than the surface 6, whichcontacts with the underside of the shoe, so that when said plate is fastened to the shoe, as shown in v Fig. 2, there is an open space 7 between the surface and the underside of said shoe.

The he'el is designated by the numeral 9 and is made of rubber or other resilient material, and embedded therein during the process of manufacture, is a lock plate 10, having an inwardly projecting flange 11 upon the top side thereof. of substantially the same shape as the retaining plate 2, and so secured to said heel as to leave an open space 12 between the underside thereof and the surface 13. I

The heel 9 is attached to the shoe' with the retaining plate 2 within the lock plate 10, at which time the flange 1l overhangs said retaining plate and lies within the open space '7 while the edge of the retaining plate 2 lies within the open space 12. When in this position the heel is locked against movement by a hinge 11 pivotally secured to the lock plate 10 by the pintle 15 and having an opening 16 therein through which projects the head of the turn button 8.

. To insure a positive and water-tight joint between the heel 9 and shoe, the outer edges of the heel are beveled as at 17.

A heel constructed as herein shown and described is capable of being readily attached and detached by the ordinary person and without the aid or assistance of skilled labor, and when so attached is rigidly secured to the shoe.

By reason of the method of attachment above described, the heel may be shifted from the'right to the left shoe, and vice versa, thereby very materially increasing the length of time that said heel can be used.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. The combination with a shoe, of a retaining plate ixed thereto, having a projecting portion thereon around the Outer edge thereof in a plane distant from said shoe;f-a heel made of resilient material; a locking plate connected with said heel and havingfa portion thereon which engages with the projecting portion of said retaining plate and means for separably securing said plates toaiiixed my signature.
